INTRODUCTION. 


Soon  after  the  establishment  of  the  Naval  Observatory  a  plan  was  formed  for  making  an  extensive 
catalogue  of  stars.  An  account  of  this  plan  may  be  found  at  pp.  [39]  to  [42]  of  the  Appendix  to  the 
annual  volume  of  the  Observatory  for  1845.  The  work  was  begun  in  1846,  with  three  meridian  instru- 
ments, the  Mural  and  Meridian  Circles  and  the  Transit  Instrument.  The  zones  observed  in  1846,  below 
30"  south,  were  usually  gone  over  but  once,  the  Mural  Circle  and  Transit  Instrument  taking  alternate  belts. 
Those  in  following  years  were  gone  over  twice,  and  generally  with  different  instruments. 

The  observations  of  zones  of  stars  were  discontinued  in  July,  1849,  as  it  was  then  found  that  the 
astronomical  force  of  the  Observatory  was  not  sufficient  to  perform  the  current  and  necessary  duties  of  such 
an  institution,  and  at  the  same  time  to  complete  the  vast  work  of  cataloguing  stars  which  had  been  under- 
taken. In  the  mean  time  the  professors  in  charge  of  the  several  instruments  had  prepared  formulae  for  the 
reduction  of  the  zones,  had  determined  and  tabulated  the  various  instrumental  corrections  necessary  for 
making  the  reductions,  and  had  begun  the  work  of  reducing.  These  reductions,  however,  were  soon 
interrupted  by  the  detachment  from  the  Observatory  of  some  of  the  officers,  and  by  the  ill-health  of  others, 
and  nothing  further  was  done  until  1859.  In  that  year  the  reduction  of  the  zone  observations  was  resumed 
by  Mr.  James  Ferguson,  late  assistant  astronomer,  who  reduced  the  zones  observed  with  the  Meridian  Circle 
in  1846,  and  which  were  published  in  1860.  In  the  summer  of  1861  copies  of  all  the  observations  of  zones 
were  made  under  the  care  of  Mr.  Ferguson,  and  they  were  put  into  the  hands  of  Dr.  B.  A.  Gould  to  revise 
the  work  already  done  and  complete  the  reductions.  He  returned  them  ready  for  printing  in  July,  1867. 

The  stars  embraced  in  these  zones  are  all  in  southern  declination,  and  for  the  most  part  between  the 
parallels  of  twenty  and  forty-five  degrees,  and  in  regions  where  as  yet  very  few  of  the  smaller  stars  had 
been  observed.  The  observing-books  indicate  that  a  large  part  of  the  observations  with  the  Mural  Circle 
were  carefully  made.  It  has  been  decided,  therefore,  to  publish  the  zones  observed  with  that  instrument, 
and  also  in  a  succeeding  year  those  observed  with  the  Transit  Instrument,  these  two  instruments  having 
been  employed  conjointly.  The  following  pages,  i  to  331,  contain  the  observations  of  the  zones  observed 
with  the  Mural  Circle  in  the  years  1846,  1847,  1848,  and  1849,  with  the  reductions  and  the  deduced 
positions  of  the  stars.  The  declinations  were  prepared  by  Professor  Coffin,  except  for  a  portion  of  the 
zones  in  1849,  as  a'so  tne  reductions  to  mean  of  wires  for  the  Transit  observations  in  1846  and  1847,  and 
the  preliminary  tables  for  the  right  ascensions  for  the  whole  period,  except  the  portions  involving  clock  and 
instrumental  corrections. 

§    2- 

THE  INSTRUMENT. 

The  following  description  of  the  Mural  Circle,  the  instrument  employed  in  making  the  observations,  is 
taken,  with  slight  changes,  from  the  annual  volume  of  the  Observatory  for  1846: 

The  Mural  Circle  was  constructed  by  Troughton  &  Simms,  of  London. 

During  the  time  of  the  zone  observations  it  remained  in  the  east  observing-room,  and  upon  the  eastern 
face  of  the  sandstone  pier,  to  which  it  was  removed  in  the  latter  part  of  1845.  This  pier  is  nine  feet  four 
inches  high,  six  feet  from  north  to  south,  and  three  feet  three  inches  from  east  to  west.  The  axis  of  the 
instrument  reaches  entirely  across  the  pier,  through  an  archway  of  thirty-two  inches  span  and  twenty-one 
inches  pitch. 

The  circle  is  placed  upon  the  eastern  end  of  the  axis,  which  is  sustained  in  part  on  friction-rollers 
supported  by  counterpoises.  It  is  five  feet  in  diameter.  The  divisions  are  upon  the  periphery  of  the  rim, 
cut  upon  a  band  of  gold,  and  5'  apart.  They  are  read  off  by  means  of  six  of  "Troughton's  Reading 


VI  INTRODUCTION  TO  THE  MURAL  ZONES. 

Microscopes,"  mounted  firmly  upon  the  face  of  the  pier,  and  adjusted,  as  nearly  as  practicable,  60°  from 
each  other.  These  microscopes  are  designated  in  the  observations  by  the  letters  A,  B,  C,  D,  E,  F.  They 
are  arranged  as  in  the  accompanying  diagram,  A  being  on  the  north  side  of  the  pier,  and  the  line  through 
the  center  joining  A  and  B  being  horizontal.  By  this  arrangement 


(the  reading  for)  B  =  (the  reading  for)  A  +  180° 

C  =  "                A  +  300° 

"               D  =  "                 A  +  120°

F  =  A  +    60°

These  microscopes  are  adjusted,  as  to  focal  length,  so  that  five  revolutions  of  the  micrometer-screw  of 
each  may  measure  one  space,  or  5'  of  the  circle.  The  micrometer  heads  are  divided  into  sixty  parts — 
reading,  therefore,  directly  to  seconds,  or,  by  subdivisions  easily  made,  to  tenths  of  seconds.  In  general,  in 
making  readings  of  the  circle,  the  seconds  a.n&  parts  are  read  from  each  of  the  six  microscopes,  and  to  these 
are  prefixed  the  degrees  and  minutes  from  A  alone.  The  mean  of  these  six  readings  constitutes  the  "  Circle 
Reading." 

For  illuminating  the  graduated  limb,  a  lamp  is  placed  behind  the  pier  in  a  line  with  the  axis  of  the 
instrument ;  the  light  from  this  lamp  passes  through  six  holes,  bored  through  the  pier,  directly  to  the  reflectors 
attached  to  the  several  microscopes.  In  this  way  a  less  variable  illumination  is  secured  than  formerly  by 
means  of  lamps  carried  in  the  hands.  The  object  aimed  at  has  been  to  have  the  same  illumination  for  the 
readings  of  the  circle,  both  in  the  observation  of  a  star  and  in  the  determination  of  the  "Nadir  Point" 
which  is  to  be  employed  in  its  reduction. 

The  circle  is  adjusted  to  a  vertical  position  by  means  of  a  plummet  suspended  on  a  fine  silver  wire, 
with  the  aid  of  appendages,  attached  to  the  telescope  known  as  "  Ramsden's  Ghosts,"  and  to  its  position  in 
the  meridian  by  observations  of  the  transits  of  circumpolar  stars. 

The  telescope  of  this  instrument  has  an  object-glass  of  four  inches  clear  aperture,  with  a  focal  length 
of  five  feet.  It  is  attached  to  an  independent  axis,  moving  within  the  axis  of  the  circle,  and  may  be  moved 
to  any  position  with  reference  to  the  graduations.  The  ends  of  the  tube,  or  the  cells  supporting  the  object- 
glass  and  the  micrometer,  are  firmly  clamped  to  the  rim  of  the  circle. 

The  eye-end  of  the  telescope  is  furnished  with  a  fixed  diaphragm,  containing  seven  vertical  wires, 
designated  I,  II,  III,  &c.,  nearly  equidistant,  and  at  an  average  interval  apart  of  iS8.4,  (in  time,)  and  one 
horizontal  wire,  which  it  is  found  convenient  to  call  the  fixed  wire.  The  adjustments  of  this  diaphragm 
have  consisted  in  placing  it  in  the  principal  focus  of  the  object-glass — turning  it  so  that  an  equatorial  star 
will  exactly  traverse  the  fixed  -wire — and,  the  circle  being  adjusted  to  an  exact  vertical  position  and  the 
telescope  directed  to  the  nadir,  moving  the  diaphragm  so  that  the  vertical  wire  IV  will  coincide  with  its 
image  reflected  from  a  surface  of  quicksilver  and  seen  by  means  of  the  collimating  eye-piece. 

In  connection  with  the  fixed  diaphragm  is  another,  movable,  with  a  micrometer-screw,  and  furnished  at 
the  commencement  of  the  year  (1846)  with  one  wire  or  spider's  line  only.  In  the  latter  part  of  February, 
in  order  to  adapt  the  instrument  to  the  work  of  cataloguing,  this  diaphragm  was  furnished  with  eight  addi- 
tional wires  parallel  to  the  original  one,  and  distributed  on  each  side  of  it  at  distances  equivalent  to  five 
revolutions  of  the  micrometer-screw.  Subsequently  the  four  nearest  to  the  middle  or  original  one  were 
removed,  those  which  remained  being  respectively  five,  fifteen,  fifteen,  five  revolutions  apart.  These  were 
changed  in  May,  1849,  to  intervals  of  five,  ten,  ten,  five  revolutions.  In  the  record  of  the  work  in  which

they  have  been  employed  they  are  numbered  1,  9,  3,  4,  5,  in  the  order  of  the  micrometer-scale,  i.  e., 
commencing  in  the  southern  part  of  the  field  of  view.  To  render  available  so  large  an  extent  of  field  in 
declination  as  is  embraced  in  this  system  of  wires,  the  eye-piece  was  also  provided  with  a  vertical  motion. 
The  adjustment  of  this  diaphragm  consists  in  making  wire  3  parallel  to  the  fixed  wire. 

The  head  of  the  telescope-micrometer  is  divided  into  100  parts,  and  is  usually  read  to  thousandths  of  a 
revolution.  It  is  adjusted  so  that  when  wire  3  is  moved  into  coincidence  with  I\\Q  fixed  wire,  the  micrometer 
reading  shall  be  nearly  3or.ooo,  3or.  indicating  the  notch  of  the  micrometer-scale  which  is  intersected  by 
the  fixed  wire.  In  making  a  micrometer  reading  that  notch  of  the  scale  is  noted  which  the  wire  used  in 
the  observation  has  passed. 

§  3- 
METHOD  OF  OBSERVING  AND  OBSERVERS. 

The  instrument  was  clamped  at  a  division  of  the  circle,  or  midway  between  two  divisions,  and  the 
microscopes  were  read,  (on  two  sets  of  division  when  the  circle  was  set  between  them,)  and  also  the 
meteorological  instruments.  These  readings  were  generally  repeated  several  times  during  the  observation 
of  a  zone.  "  The  transits  were  observed  by  the  eye  and  ear  method.  The  bisections  for  declination  were 
made  at  one  of  the  transit  wires  I,  II,  III,  IV,  &c.,with  one  of  the  micrometer  wires  1,  2,  3,  4,  5.  The 
observations  were  recorded  in  blank-books,  the  form  of  which  is  given  in  the  Appendix  of  the  annual  volume 
for  1845,  under  the  heads  O  and  /'.  The  following  notes  are  taken  from  one  of  Professor  Coffin's  observing- 
books : 

a.  "The  transit  wire  on  which  the  micrometer  bisection  is  made  is  the  IV  wire  if  the  transits  were  observed 

upon  it  or  upon  wires  both  sides  of  IV;  otherwise  the  wire  observed  on  nearest  IV.     The  exceptions 
are  noted." 

b.  "The  micrometer  wire  when  not  noted  is  wire  3." 

c.  "  The  minute  belongs  to  the  first  transit  wire  observed." 

The  above  rules  were  followed  by  Professor  Coffin  in  all  his  observations,  and  it  appears  that  the  other 
observers  followed  the  same  rule  with  regard  to  the  minute  of  the  transit. 

The  observers  were  Professor  J.  H.  C.  Coffin,  U.  S.  N.,  who  observed  from  the  beginning  until  the  end  of 
the  work  in  1849;  Lieutenant  T.  J.  Page,  U.  S.  N.,  who  observed  from  the  beginning  until  January  4, 1848; 
and  Lieutenant  Charles  Stecdman,  U.  S.  N.,  who  observed  from  December  15,  1847,  until  June  21,  1849. 
The  initial  of  the  observer  is  placed  at  the  beginning  of  the  zone  together  with  the  date  of  observation. 

The  adjustments  of  the  instrument  were  made  by  Professor  Coffin,  who  also  made  the  observations  for 
determining  the  value  of  a  revolution  of  the  telescope  micrometer  and  the  corrections  of  the  micrometer 
wires. 

Professor  Coffin  furnishes  the  following  corrections  to  be  applied  to.  the  micrometer  readings,  derived 
from  the  published  volumes  of  the  Observatory  for  the  years  1846  to  1850:

3.  Reduction  of  the  other  Micrometer  Wires  to  Wire  3. 

These  reduce  the  readings  for  observations  with  the  several  wires  to  what  they  would  have  been  if  wire 
3  had  been  used. 

During  1846  and  1847  wire  *>  could  not  be  brought  into  coincidence  with  the  fixed  wire,  so  that  the 
reductions  for  it  have  not  been  determined;  and,  therefore,  except  in  the  earlier  zones  of  those  years,  that 
wire  has  not  been  used.  In .  a  few  of  the  earlier  observations  of  Lieutenant  Steedman  he  has  used  a  wire 
which  he  calls  G,  of  which  there  is  no  account.  The  declinations  derived  from  observations  with  these 
two  wires  are,  therefore,  imperfectly  determined;  so  also  from  observations  with  wire  ],  in  zones  158-161 
and  178-187. 

The  periods  of  the  following  table  are  those  in  which  there  was  no  known  disturbance  of  the  wires,  and 
the  several  determinations  agree  satisfactorily  with  each  other.

These  several  reductions,  except  the  first,  can  readily  be  combined  for  any  zone  for  each  micrometer 
and  transit  wire. 

The  equatorial  intervals  of  the  transit  wires  from  their  mean  were  derived  by  Professor  Coffin  from  the 
zone  observations  in  1846  and  1847  for  each  5*  of  the  field  as  indicated  by  the  micrometer  reading,  and 
the  transits  in  those  years  reduced  by  him  to  the  "mean  of  wires;"  but  the  papers  containing  tables  of  these 
intervals,  as  well  as  Dr.  Gould's  tables  for  the  subsequent  years,  cannot  now  be  found. 

The  periods  during  which  the  intervals  may  be  regarded  as  constant  are  sufficiently  indicated  by  the 
notes  of  changes  and  disturbances  of  the  wires  on  page  vin. 

Dr.  Gould's  determinations  of  the  reduction  of  the  "mean  of  wires"  to  the  meridian  for  the  several 
zones  have  also  been  mislaid,  so  that  they  appear  in  the  aones  only  in  combination  with  other  reductions. 

The  observations  with  the  Mural  Circle  were  differential  in  right  ascension;  and  these  reductions  could 
be  obtained  only  by  means  of  right  ascensions  of  stars  of  comparison,  supplied  either  by  observations  with 
the  other  instruments  or  by  the  catalogues. of  stars.  The  earlier  zones  observed  with  the  Mural  Circle  and 
Transit  Instrument  in  1846  unfortunately  overlapped  on  one  side  only,  owing  to  some  misunderstanding  as 
to  the  declinations  at  which  each  instrument  should  be  set;  so  that  the  other  side  of  each  is  almost  entirely 
deficient  in  common  stars.  This  deficiency  has,  however,  been  supplied  by  observations  made  subsequently 
by  Professor  Yarnall. 

§4- 

In  the  following  tables  are  collected  the  clock  corrections,  with  the  hourly  rates;  the  observed  coinci- 
dence of  wire  3  with  the  fixed  wire,  the  adopted  values  of  a  revolution  of  the  micrometer-screw,  and  the 
readings  of  the  circle  for  the  zenith  point.  These  quantities  have  been  taken  from  the  volumes  of  the 
Observatory  for  the  years  1846,  1847,  1848,  and  1849. 

The  clock  corrections  are  copied  from  the  observations  with  the  Meridian  Circle.  In  the  copy  of  the 
earlier  zones  prepared  for  Dr.  Gould  the  quantities  m,  n,  and  c,  as  well  as  the  clock  corrections,  were  taken 
from  the  Meridian  Circle  observations,  and  were  printed  before  the  error  was  noticed.  They  do  not  belong 
to  the  Mural  Circle  zones. 

The  coincidence  of  wire  3  with  the  fixed  wire  was  determined  on  almost  every  day  of  observation 
from  six  or  eight  contacts  (alternately  on  each  side)  at  the  vertical  wire  IV.  Interpolated  values  are 
inclosed  in  brackets. 

The  value  of  one  revolution  of  the  screw  of  the  telescope  micrometer  was  determined  by  means  of  the 
collimating  eye-piece  and  a  basin  of  mercury.  The  observations  will  be  found  given  in  detail  in  the  Intro- 
ductions of  the  several  volumes.  The  values  there  given  are  for  the  middle  of  the  field.  Professor  Coffin 
assumed  as  the  value  for  the  part  of  the  field  indicated  by  the  micrometer-reading  m, 

R  =  RQ  4.  2  (,,i  —  30)  AjR 
and  found  the  following  values  of  JJ?  ;

Its  value  would  probably  be  affected  whenever  the  telescope  was  undamped  from  the  rim  of  the  circle 
and  moved.  This  was  done  January  2  and  September  19,  1848,  and  January  i,  1849. 

The  determination  of  the  nadir  point  was  made  by  means  of  the  collimating  eye-piece.  The  telescope 
being  directed  downward,  the  circle  was  moved  by  one  of  the  tangent-screws  until  the  fixed  wire,  illumi- 
nated by  means  of  this  eye-piece,  coincided  with  its  image  reflected  fiom  a  surface  of  mercury;  then'the 
circle  reading  corrected  for  runs  and  errors  of  division  constitutes  the  nadir  point.  Each  determination 
consists  of  several  such  coincidences  and  circle  readings,  the  wire  and  its  image  being  brought  into  coinci- 
dence from  opposite  sides.

INTRODUCTION  TO  THE  MURAL  ZONES.  xix 

§5- 
METHOD  OF  REDUCTION. 

The  magnitudes  of  the  stars,  the  seconds  of  the  observed  times  of  transit  in  the  columns  I,  II,  III, 
&c.,  the  micrometer  readings,  the  micrometer  wires  used,  and  the  transit  wires  at  which  the  bisections  were 
made,  have  been  taken  from  the  observing-books,  and  the  proofs  compared  directly  with  them  and  corrected 
to  agree  with  the  records  of  the  observers.  The  minutes  of  the  transits  have  been  changed,  when  necessary, 
so  as  to  adapt  them  to  the  "  mean  of  wires." 

The  method  of  reduction,  as  arranged  by  Professors  Coffin  and  Hubbard,  is  nearly  the  same  as  that 
described  by  Mr.  Ferguson  in  his  Introduction  to  the  Meridian  Circle  Zones  of  1846,  published  in  1860. 
The  differences  arise  from  the  different  construction  of  the  two  instruments. 

i.  The  times  of  transit  of  a  star  were  first  reduced  to  the  mean  of  wires,  using  for  each  wire  the  reduc- 
tion for  the  zone  in  the  part  of  the  field  indicated  by  the  micrometer  reading; 
T,  representing  the  clock  times  of  transit  of  the  mean  of  wires  ; 
k,  the  clock  correction  at  that  time; 
/,  the  reduction  of  the  mean  of  wires  to  the  meridian  for  the  middle  of  the  field,   or  at  30*  of  the 

micrometer  ; 

M,  the  reduction  to  1850.0  for  the  right  ascension  and  declination  of  the  middle  of  the  field; 
J/and  AM,  the  variations  of  /and  M  for  the  distance  of  the  star  in  declination  from  the  middle  of  the 
field,  or,  —  (in  —  3or)  in  terms  of  the  micrometer,  m  being  the  micrometer  reading; 

and  putting 


ai  =  t  +  M.  a.2  =  I  +  J7  +  AM 

the  right  ascension  of  the  star  is 

"  =    T  -\-  «!  +  «2 

The  preliminary  work  consisted  in  the  preparation  of  tables  for  each  zone  containing  at  for  each  iom- 
of  clock-time,  and  a2  for  each  5  or  10  revolutions  of  the  micrometer,  and  at  such  intervals  of  time  as  was 
requisite.  The  columns  at  and  «2  were  then  readily  filled  by  an  easy  interpolation. 

The  column  «2,  which  is  printed,  includes  corrections  for  erroneous  values  of  k  used  in  the  earlier 
zones  in  forming  the  tables  of  al  ;  and  in  some  zones  a  constant  appears  to  have  been  added  to  one  and 
subtracted  from  the  other  so  that  the  signs  should  be  uniform. 
2.  C,  representing  the  first  circle  reading  for  a  zone; 
Z,  the  zenith  point  ; 
r,  the  refraction  for  the  zenith  distance  (C  —  Z)  and  the  first  readings  of  the  barometer  and  ther- 

mometer ; 
M,  the  reduction  to  1850.0  for  the  declination  of  the  middle  of  the  zone,  or  30',  and  the  right  ascen- 

sion of  its  commencement,  or  an  exact  iom  preceding; 
///„  the  micrometer  'reading  for  coincidence  of  3  with  the  fixed  wire;  or,  in  1849,  the  reading  of  3 

to  correspond  wkh  Z  =  20°  o'  o"  : 
the  constant  of  declination  for  the  zone  is 

A  =  38°  53'  39".2S  -  (C-  Z)  -  62".75  («,  -  30')  -  r  +  M+  30'  +  «'  +  n" 

30'  and  the  arbitrary  constants  «'  and  «"  being  added  so  that  all  the  reductions  shall  have  the  same  sign  as 
Z>0.  Omitting  these,  Z>0  is  the  mean  declination  of  wire  3  at  the  commencement  of  the  zone  and  for  the 
micrometer  reading  3or.ooo.  n'  and  ;;"  were  omitted  from  the  copy  prepared  for  the  printing,  and  the  papers 
containing  them  are  missing. 

The  micrometer  reading  for  each  star  was  corrected  for  eccentricity  of  the  micrometer-head,  and  reduced 
from  the  recorded  micrometer  and  transit  wires  to  wire  3  at  transit  wire  IV,  and  to  the  meridian  by  means 
of  the  tables,  pages  ix  and  x.

A  table  for  each  or.oi  of  in  facilitated  the  preparation  of  this  column.

A\r,  the  difference  of  refraction;  and  •    . 

A\M,  the  difference  of  M,  for  the  distance  of  the  star  in  declination  from  the  middle  of  the  field,  or

AR  and  R0  are  given  on  pages  xi  and  xni-xvm. 
The  declination  of  the  star  is 

3  =  A  +  /  +  Ji  +  d, 

The  preliminary  work  for  each  zone  consisted  in  computing  D0  and  preparing  tables  of  d\  for  each 
10™  of  clock-time,  and  of  d^  for  each  5'  or  ior  of  m,  and  at  such  intervals  of  time  as  was  requisite.  These 
columns  were  then  readily  filled  by  interpolation. 

The  columns  i  and  of  right  ascension  and  declination  include  also  corrections  for  errors  of  exact  revo- 
lutions of  the  micrometer,  and  of  minutes  or  exact  seconds  in  the  times  of  transit,  which  Dr.  Gould,  in  the 
thorough  scrutiny  which  he  made,  detected  by  comparison  with  other  zones  or  catalogues.  Such  cases  are 
noted  in  the  margin.  Some  of  the  few  errors  of  the  copyist  were  detected  by  him  in  the  same  way  and 
corrected. 

Notes  by  the  observers  of  doubtful  observations  are  indicated  in  the  text  by  a?;  but  the  degree  of 
doubt,  as  is  or  ios  in  a  transit,  or  of  ir  of  the  micrometer,  are  omitted;  so  also  are  notes  of  other  stars 
seen  whose  positions  were  only  estimated.  The  numbers  of  stars  identified  in  the  British  Association 
Catalogue,  and  in  Oeltzen's  Catalogue  of  Argelander's  southern  zones,  which  were  added  by  Dr.  Gould,  are 
also  omitted,  as  it  was  inconvenient  to  print  them;  and,  moreover,  these  catalogues  and  the  zones  being 
referred  to  the  same  epoch,  the  stars  which  are  common  to  them  may  be  recognized  with  little  trouble. 

The  quantities  of  reduction  and  the  deduced  positions  of  the  stars  have  been  printed  as  in  the  completed 
copy  returned  by  Dr.  Gould. 

It  having  been  decided  to  publish  the  Zones  observed  with  the  Mural  Circle  and  Transit  Instrument, 
the  supervision  of  the  work  .was  put  into  my  hands  by  Admiral  Sands,  Superintendent  of  the  Naval  Obser- 
vatory, in  April,  1871.  It  has  been  my  endeavor  to  give,  in  the  first  place,  an  exact  copy  of  the  observa- 
tions. For  this  purpose  the  proofs  were  compared,  as  has  been  already  mentioned,  with  the  hand-books  of 
the  observers.  The  results  deduced  by  Dr.  Gould,  and  his  notes  to  the  observations,  have  been  printed 
without  any  change.  A  few  cases  occur  where  the  results  will  be  changed  on  account  of  changes  in  the 
copy,  but  in  nearly  every  case  the  correction  will  be  indicated  by  a  comparison  t>f  the  notes  and  the  obser- 
vations. It  was  also  the  intention  to  print  the  tables  of  reduction  which  had  been  prepared  for  each  zone, 
but,  unfortunately,  up  to  the  present  time,  these  tables  cannot  be  found;  should  they  be  found  hereafter 
they  will  be  published  either  with  the  Transit  Zones  or  in  a  separate  Appendix. 

In  reading  the  proofs  I  have  been  assisted  from  page  i  to  57  by  Mr.  O.  Stone,  from  page  57  to  73  by 
Mr.  Harrison,  and  from  page  96  to  the  end  by  Mr.  A.  N.  Skinner. 

I  am  much  indebted  to  Professor  J.  H.  C.  Coffin,  Superintendent  of  the  Nautical  Almanac,  for  informa- 
tion concerning  the  Zones,  and  for  assistance  in  preparing  the  Introduction.

ERRATA. 


In  printing  the  "seconds  of  transit"  in  the  zones  observed  by  Lieutenant  Page  in  1846  the  ciphers 
should  have  been  omitted,  as  they  do  not  occur  in  the  observing-book.  It  appears  that  both  Lieutenant 
Page  and  Lieutenant  Steedman  at  first  were  inexperienced  in  observing  transits,  and  in  their  earlier  zones 
only  the  even  second  was  observed. 

In  the  case  of  Zone  107  several  circle  readings  were  omitted  by  the  copyist,  and  in  the  single  one 
copied  an  error  of  —  20"  was  made  in  copying  the  reading  of  microscope  F,  thus  introducing  an  error  of 
—  3"_3  into  this  circle  reading.  .  It  is  probable  that  all  the  declinations  of  this  zone  are  systematically  in 
error  by  this  amount. 

In  numbering  the  zones  the  number  180  is  repeated  at  the  end  of  Zone  181,  and  Zone  182  is  called 
181,  and  so  on  to  the  end. 

Page  3,  under  "Remarks"  in  the  last  note,  omit  the  25. 

Pages  it  and  12,  under  micrometer,  for  E.  W.  read  F.  W.,  which  denotes  the  fixed  wire. 

Page  72,  for  September  24  read  September  28. 

Pages  173  to  217,  under  the  head  of  corrections,  the  o11  should  have  been  omitted.

*This  reading  has  been  assumed  as  too

Z.,  March  7,  1849.

these   transits   is   to   suppose 
transit  over  T.  II  recorded  over 
T.  Ill,  and  as  34'4,  not  I4".4  ; 
and  transit  over  T.  VI  as  50*.  3
